### Definite Integrals Involving Odd and Even Functions

If f is an even function, that is, f (–x) = f (x), and is continuous on [–a, a], then

If f is an odd function, that is, F (x) = – f (–x), and is continuous on [–a, a] then

### Example 1

Evaluate

Since f (x) = cos x is an even function,

Verify your result with a calculator.

### Example 2

Evaluate

Since f (x)=x4 – x2 is an even function, i.e., f (–x ) = f (x), thus

Verify your result with a calculator.

### Example 3

Evaluate

Since f (x) = sin x is an odd function, i.e., f (–x)= – f (x), thus

You can also verify the result with a calculator.

### Example 4

If for all values of k, then which of the following could be the graph of f ? See Figure 11.3-1.

Thus f is an even function. Choice (C).
